Question about BenQ MP770 DLP Projector
When the projector (bought April 07 but low useage - every couple of weeks for a few hours) is first powered up, thin parallel vertical lines appear across the screen. They're black but seem to have little flashing lights too. No other indicator lights (like the lamp or the temp) are on, so don't think it's the bulb. The first time it happened they disappeared after about 15 mins. The second time, still there after an hour. Tonight, they disappeared when I turned it off and back on. Any ideas anyone? Thanks.

omg, I just figured out why OUR projector was doing this! There was an adaptor plugged into it that we use to hook it up to cable to watch games/tv shows sometimes...once I unplugged that from the projector the lines dissapeared!

This is a typical BenQ Mp Series problem , and will notice that it will start of intermittently , but later on the white line will appear every single time.
This can only be fixed by replacing the Mainboard of the MP710/720/721

After 2 years I finnaly solved the problem. There was a flaw in the lamp´s temperature circuit. A technician disassambled my BENQ PB8253 unit and fixed the problem. Charged me US$ 75.00. I´m in Brazil.
Hope this can help.
